In total, Serena has 69 WTA titles under belt. Work!

After taking down her opponent, Serena gave her winning speech, in which she said,

"Thank you Simona for playing such a good match today, and always being such an incredible opponent and incredible sportswoman. I'm always honored to play against you and always have such a wonderful match whenever we play.”

She added,

"I've also got to say, I don't get support everywhere I play, but I get so much support here in Cincinnati that it makes me want to come back forever and ever, so thank you to all the fans today!"

Next up for Serena? She will hit the tennis court at the U.S. Open kicking off August 31st in NYC.
